The classification system was used to stratify estuaries in NSW for the development of reference conditions and the design of a sampling program of chlorophyll a, turbidity and associated water quality parameters to assess estuary health. ; ; Catchment rainfall, runoff and evaporation were also required to support estimation of the loads of Total Suspended Solids, Total Nitrogen and Total Phosphorus exported from estuary catchments.; ; Monthly time series of estimated stream flow, surface flow and base flow were modelled for 197 coastal NSW catchments. Stream flow was estimated using the 2CSalt model. {"type": "Polygon", "coordinates": [[[154.0, -37.5], [154.0, -28.0], [148.0, -28.0], [148.0, -37.5], [154.0, -37.5]]]} 148.0 154.0 -37.5 -28.0 Data Quality Statement documentDigital PDF Estuary Catchment Streamflow and Surface Runoff: 1975-2007 documentDigital ZIP
